چکیده
The deployment of low earth orbits is seen as a promising way enlarging data capacities well high rates. Catering to these interests, optical communication presents possible ways larger bandwidth than microwave communication. current generation mainstream systems are classified coherent and incoherent systems, in particular, have received more attention owing their receiving sensitivity. This study investigates digital transceiver, based on binary phase-shift keying technology. As demodulation will be affected by considering the Doppler shift effect demodulation, ± GHz can compensated adopting two-stage frequency offset compensation. Moreover, leveraging fast filtering algorithm considerable amount resource consumption saved its engineering implementation, sensitivity significantly enhanced via high-speed parallel error-correction codec low-density parity-check

متن کاملOn Prototyping Multi-Transceiver Free-Space-Optical Communication Structures
Wireless networking has conventionally been realized via radio frequency (RF) based communication technologies. However, the capacity of these networks are limited by the availability of the RF spectrum. Free-Space-Optical (FSO) communication has the potential to deliver wireless communication links at optical-level speeds. Although it has the advantage of the high speed modulation, maintenance...
متن کاملTransceiver Design and Performance Analysis of Free-space Optical Communication
In free-space optical communication links, atmospheric turbulence causes fluctuations in both the intensity and the phase of received light signal, impairing link performance. In this paper, we describe several communication techniques to mitigate turbulence-induced intensity fluctuations, that is signal fading. These techniques are applicable in the regime in which the receiver aperture is sma...
متن کاملA Novel Active Feedback Frequency Compensation Scheme for Two-Stage OTA
A novel active feedback frequency compensation scheme is presented in this work. Based on the proposed technique, an amplifier with two main poles in its frequency bandwidth can be easily compensated by introducing a pole-zero pair in a local feedback. The proposed method is mathematically analyzed and then based on the derived formulations, a design procedure is established. The capability of ...
